Questionable symptoms

Emily • Pregnant with #3! Due May 6th 2015
I'm 7dpo. Here's what I've been experiencing the past 5 days ...
​Cold like symptoms.. Started with a Sore throat and have had a runny nose since 
​Broke out in acne (on my neck..?) two days ago 
​Woke up with a charlie horse yesterday night
​Had diarrhea today (tmi sry) 
​Today and yesterday have been extremely tired 
​Today I'm feeling lightheaded and weak and shakey
​ 
​Are these pregnancy symptoms? Anyone else had any if these strange things or am I just sick?! Agh!!
